JOSEPH M. TOWNE, OF EAST ORANGE, NEW JERSEY.

OPEN SPRING-CLIP FOR TEMPORARY BINDERS.

To (1% whom it may concern:

Be it known that I, J OSEPH M. TOWNE, a citizen of the United'States, residing at East Orange, Essex county, New Jersey, have invented certain new and useful Improvements in Open Spring- Clips for Temporary Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in temporary binders, and relates more particularly to binders of the type which are specially adapted to receive pamphlets, leaflets or catalogues, though also capable of use with loose leaves.

The primary object of the invention is to provide means whereby one or a plurality of individual pamphlets may independently be easily and quickly placed in connectedposition and removed from the binder without disconnecting the usual posts which connect the binder covers and serve as the medium of securing the pamphlets to the covers.

In the drawings: Figure 1 is a longitudinal vertical sectional view of a binder showing the present invention applied thereto; Fig. 2 is a fragmentary perspective view of a pamphlet or book to which the present invention is applied, but in detached relation to the binder; Fig. 3 is a top plan view of the clip forming the present invention; and Figs. 4, 5, and 6, are similar views of various modified forms of the invention.

The cover of the binder designated 1, in the drawings has the usual posts 2, which parts may be of any desired or preferred form or construction. The clips which form the present invention are formed of integral thin sheets or plates of spring metal and consist of a body portion 1, having a pair of arms 2 projecting outwardly from the front side edges thereof, which arms are bifurcated at 8, to form a pair of spring gripping fingers 4, the inner faces of the fingers being preferably inclined outwardly at 5 to form flared mouths to allow the fingers to be easily and quickly placed on opposite sides of the posts 2. The intermediate portions of the fingers are formed with registering arcual cut-out portions 6 to receive opposite sides of the posts- The outer faces of the fingers are also inclined outwardly at 7 and meet the inclined por- Specification of Letters Patent.

tions 5 in a point whereby to form sharp penetrating ends 8.

In applying the clip to a pamphlet or book, the latteris spread open at its center and the points 8 are then moved to penetrate the bound edge of the pamphlet or book so that the body 1, occupies the position depicted in Fig. 2, in which same engages on the inner side of the bound edge of the book, while the arms 2 extend outwardly and are disposed on the outer side of the bound edge of the book, in which position the spring fingers 4, 4 are forced into engagement with the posts 2 to thereby cause the fingers to snap over opposite sides of the posts. Obviously, in the manner described the spring fingers may be easily and quickly applied to and removed from the posts.

While the invention is particularly designed for the binding of pamphlets, still it will be apparent that it can be used equally well with single loose leaves, by attaching the clips in any suitable manner to the loose leaves.

In Fig. 5, of the drawings, the structure is substantially identical with that shown and described in connection with Fig. 3, excepting that the mouths of the fingers and the inner faces of the latter extend at an incline or angle to the plane of the arms 2, which enables the clips to be engaged with the posts by moving the clips diagonally of the binder.

In Fig. 4 of the drawings, but one pair of spring fingers is employed, the other arm, designated 2 in Fig. 4, having a true right-angular mouth 3 which merely frictionally engages with the post that arm 2' corresponds to.

In Fig. 6 of the drawings, the arm 2 is formed to have a single large spring finger 4, the mouth 3 of which extends parallel to the longitudinal axis of the body of the clip, while the arm 2 has a similarly disposed mouth. Arm 2 has a cut-out part 9 which receives one side of the companion post, and further has a slot 10 which forms a spring finger 11, which grips the post in an obvious manner.

The above illustrate various difierent ways in which the invention can be carried into practice and are to be considered in the light of examples and not exhaustive enumeration. I

What is claimed is:

1. A'clip for holding pamphlets and the like in temporary'binders consisting ota spring plate having a pair of integral arms projecting outwardly therefrom, said arms being bifurcated to form a pair of spaced fingers which receive the posts of the binder in said space and Which are adapted to snap into engagementwith the posts.

2. A clip for holding pamphlets and-the like in temporary binders consisting of a spring plate having integral arms that are each bifurcated to form a'pair of fingers, said fingers having registering concave portions which are adapted to receive the posts of the binder.

3. A clip for holding pamphlets and the like in temporary binders consisting of a spring plate having arms which project outwardly therefrom, said arms being bifur- "cated to iorm spring fingers which are adapted to snap intoengagement with the binder posts.

i. A clip for holding pamphlets and the like in temporary binders "consisting or a spring plate having arms Which are integral therewith and project outwardly therefrom, each of said arms being bifurcated to form a pair of spring fingers, the inner Gbpies of this patent may be obtained for faces of the fingers having registering concave portions to receive the posts of the binder, and the free end portions of the fingers being tapered to form flared mouths which lead into the bifurcations and to also form points which penetrate the pamphlet A at the bound edge thereof;

have resilient members formed therewith to snap into engagement with the posts of the binder to secure the arms thereto. 7

In testimony whereof I aiiix my signature inpresence of two witnesses.
